If you've been appointed as an executor or administrator of an estate in California, one of your first legal responsibilities is completing the estate inventory forms. Getting this wrong can delay probate, trigger court objections, or even expose you to personal liability. Understanding how to fill out estate inventory forms in California probate court isn't just paperwork it's the foundation that every other step in the probate process depends on. This guide walks you through each part of the process, from gathering asset information to filing with the court.

What Is an Estate Inventory Form and Why Does the Court Require It?

An estate inventory form is a legal document that lists every asset owned by the deceased person at the time of their death, along with each asset's fair market value. In California probate, this form gives the court a complete financial picture of the estate. It protects beneficiaries by making sure nothing is hidden or overlooked, and it protects you as the executor by creating a documented record of what you're managing.

The California Probate Code requires this filing under Sections 8800–8802. Without it, the court cannot move forward with distributing assets, paying debts, or closing the estate.

When Do You Need to File the Inventory in California Probate?

You must file the estate inventory within four months after you receive your Letters Testamentary or Letters of Administration. That document is the court order giving you authority to act on behalf of the estate. The four-month deadline is strict, and missing it can result in the court requiring you to explain the delay or, in serious cases, removing you as the personal representative.

If you need more time, you can file a request for an extension before the deadline passes. But don't rely on extensions as a habit courts expect you to work diligently.

Which Forms Do You Need to Complete?

The primary form is Form DE-160, called the Inventory and Appraisal. This is the document where you list each asset and its value. Depending on the complexity of the estate, you may also need:

  • Form DE-160 (pages 1–3): The main inventory listing all property, bank accounts, investments, and personal belongings.
  • Form DE-161: An attachment for listing additional assets if they don't fit on the main form.
  • A certified appraiser's report: Required for real estate, business interests, collectibles, and other assets that need professional valuation.

You can learn more about the DE-160 form and what each section asks for before you start filling it out.

How Do You Fill Out Each Section of the DE-160 Form?

Section 1: Real Property

Real property means land and buildings. List the full street address, the legal description from the deed, the assessor's parcel number (APN), and the fair market value as of the date of death. California requires a probate referee a court-appointed appraiser to value real property, not the executor. You'll select a referee (or the court assigns one), and they'll provide the appraised value that goes on the form.

Section 2: Stocks, Bonds, and Other Securities

Include the name of each security, the number of shares, the exchange where it's traded, and the fair market value on the date of death. Use the closing price on the date of death (or the preceding trading day if the person died on a weekend or holiday). The probate referee typically handles these valuations as well.

Section 3: Cash and Bank Accounts

List each bank account with the financial institution's name, account type (checking, savings, CD), account number, and balance as of the date of death. For cash held at home or in a safe deposit box, note the amount and location. Bank statements are your best documentation here.

Section 4: Household Furniture, Fixtures, and Personal Effects

This covers furniture, art, jewelry, electronics, vehicles, clothing, and other personal belongings. You need to describe each item or group of similar items and provide the fair market value not replacement cost, but what someone would reasonably pay for the item in its current condition.

Section 5: Other Miscellaneous Property

This section catches everything else: business interests, promissory notes owed to the deceased, intellectual property, cryptocurrency, life insurance payable to the estate, retirement accounts with no named beneficiary, and any other assets. Be thorough. Omitting an asset, even accidentally, can create problems later.

How Should You Determine Fair Market Value for Each Asset?

Fair market value is the price a willing buyer would pay a willing seller, both with reasonable knowledge of the relevant facts, on the date of death. This is different from what the person originally paid, what an insurance company says it's worth, or what you think it might sell for in a rushed sale.

For assets that need a probate referee, you don't set the value yourself the referee does after reviewing the property. For assets under $10,000 in total value, the personal representative can sometimes list values without a referee, but the rules are specific. Review the California executor requirements and asset valuation guidelines to understand what applies in your situation.

Common valuation sources include:

  • Bank and brokerage statements dated on or near the date of death
  • County assessor records for real property (though the referee's appraisal controls)
  • Professional appraisals for jewelry, art, antiques, and collectibles
  • Kelley Blue Book or similar guides for vehicles
  • Business valuations from a qualified professional for partnerships, LLCs, or sole proprietorships

What's the Difference Between the Estate Inventory Form and the Accounting Form?

People sometimes confuse the inventory with the accounting, but they serve different purposes and are filed at different times. The inventory is a snapshot of what the estate held on the date of death. The accounting (filed later using Form DE-165 and related schedules) shows what happened to those assets over time income received, expenses paid, gains or losses from sales, and distributions to beneficiaries.

If you're unsure which form you need right now, this comparison of the estate inventory form versus the accounting form breaks down the differences clearly.

What Are the Most Common Mistakes on California Estate Inventory Forms?

Errors on inventory forms are more frequent than you'd expect. The most common ones include:

  • Listing assets at purchase price instead of date-of-death value. The court doesn't care what Grandpa paid for his house in 1985.
  • Forgetting jointly held property. Depending on how title is held, some jointly owned assets may still need to be listed.
  • Omitting digital assets. Cryptocurrency, online payment accounts, and digital media libraries are estate property too.
  • Using estimated values without documentation. The court expects values backed by statements, appraisals, or referee reports.
  • Missing the filing deadline. The four-month window goes fast, especially if you're waiting on financial institutions or referees.

These issues can lead to court objections, personal liability, or removal as executor. A detailed look at common mistakes on California estate inventory forms can help you avoid them before you file.

Do I Need a Probate Referee for Every Asset?

No. A probate referee must appraise certain assets mainly real property, closely held business interests, and items whose value isn't easily determined from public records. But some assets are valued by the personal representative instead: cash, bank accounts, publicly traded securities, and certain other assets where the value is straightforward. The California Courts self-help guide on probate offers additional context on when a referee is and isn't required.

How Do I File the Completed Forms with the Court?

Once you've completed the inventory and received appraisals from the probate referee:

  1. Make copies of the completed DE-160 (and DE-161 if needed) for your records.
  2. File the original with the probate clerk in the county where the estate is being administered.
  3. Serve a copy on each beneficiary and any interested parties, as required by Probate Code Section 8800.
  4. Keep proof of service you may need to show the court you notified everyone properly.
